River Monitoring

River monitoring supports many different activities – from determining water reserves to designing flood defences, and even to sports / leisure uses. As part of monitoring, the data collected include water currents, depth, and discharge – the net volume of water transported downstream.
After 1990, river discharge measurements changed from mechanical to acoustic instruments. For measurements made from moving boats and floats, Teledyne RD Instrument’s (TRDI) river Acoustic Doppler Current Profilers (ADCP) have become the de-facto standard. The ADCP is accurate, samples rapidly, and displays discharge results as soon as the river section is complete. Rich views of the currents come from high-density sampling through the water column and along the boat path. Stemming from these advantages, TRDI has an unmatched user /experience base and a best-in-class reputation for reliable products and dependable data quality.
